interpolation functions

Hello,
I am using the Gridded3DSet and some sample data to generate shapes. However, I am wondering what kind of interpolation function is used to generate the surface (what's going on between the data points). Is there any way that I can choose another method to interpolate between the points? Is it the resample method (i am not very clear on how to use it)? 

thanks very much,
john
